ABSTRACT:
A method and apparatus for automatically welding and handling mash welded tailored blank composites. The method comprises the steps of transferring first and second sheet component parts from respective input stacks to an assembly table of a mash welding machine. The sheet components are disposed in an overlapping lap joint configuration and the lap joint is welded along a linear weld seam thus defining a welded blank. The welded blank is conveyed in a timed step manner from the welding machine to an output stacking machine via a magnetic stepping conveyor and the blank is transferred from the conveyor to an output stack of completed blanks with a stacking machine. An apparatus is provided to carry out the method.
